The automatic flushing procedure takes 30 minutes and consists of six similar sequential steps,
each of which includes:
a)
1 minute
- pumping and circulation of flushing solution in the device (flushing unit
included);
b)
4 minutes
- hold-up of the flushing solution in the device (flushing unit is turned off);
After completion of all the six automatic flushing cycles, the LED in the device starts flashing in
blue, indicating that the PUMPING and HOLD-UP procedures of the flushing solution are completed.
Next, the user needs to disconnect the flushing unit and connect the device according to the usual
OPERATION scheme (see Fig. 7.10). In this mode, it is necessary to carry out the WASHING OUT
procedure and rinse the device with cold tap water to wash out the dissolved contaminants and residues
of the citric acid flushing solution from the device. The WASHING OUT procedure must be
performed within 10 minutes. At this time, any electrical treatment of water is turned off (the
electrochemical module is turned off), and the LED flashes green. After 10 minutes, the WASHING
OUT mode is automatically turned off (the green LED flashes) and the device enters the normal
OPERATION mode.
At this point, the FLUSHING procedure is complete!
The device is ready for normal use in OPERATION mode again!
Some features of the FLUSHING mode.
u
The user can always pause the automatic FLUSHING mode and start it again by repeatedly
pressing the on/off button of the flushing unit (Fig. 22.23 - 8). This function allows the user to
pause the FLUSHING mode if there are problems with pumping the flushing solution into the
device and resume this mode again.
u
FLUSHING mode is non-volatile and priority. That is, when the network disappears and when
it reappears, the device will automatically enter the stage of the FLUSHING mode from which
it was removed by disconnecting the network. This protects the user from the risk of accidental
ingestion of a citric acid flush solution in the body if the FLUSHING mode is violated.
u
Important! If during the flushing of the device there were any malfunctions that could disrupt
the FLUSHING mode, please repeat the flushing procedure before using the device. If faults
are detected during the FLUSHING mode, it is necessary to additionally make sure that the
flushing solution has been successfully washed out with tap water from the device for 10
minutes before using the device in normal mode.
Important! To increase the useful life of the flushing unit, we recommend that after maintenance of
the device, thoroughly rinse the intake unit and the accumulation tank of the flushing unit, as well as
the hoses for supplying the flushing solution with warm tap water, to clean them of residues of citric
acid crystals. After flushing, all elements of the flushing unit must be dried and removed before the
next flushing. The flushing procedure of the key elements of the flushing unit must also be repeated
at the beginning of future flushing procedures to ensure the smooth operation of the flushing unit.
